Police learned of McGee's alleged offenses after her friends at a youth group church meeting asked her about their relationship, according to an arrest affidavit. She told her friends that she had been having a sexual relationship with McGee for the past year.

After the alleged victim's parents learned of the relationship, the victim told Round Rock police that she began having sex with McGee in June 2014 when she was 13 years old.

McGee allegedly had sex with the underage girl in his church office, a storage unit, at his home while his wife was away and a hotel in Round Rock.
